Large granular lymphocyte leukemia.
Clonal diseases of large granular lymphocytes (LGLs) represent a spectrum of clinically rare lymphoproliferative malignancies arising from either mature T-cell (CD3(+)) or natural killer (NK)-cell (CD3(-)) lineages. The clinical behavior of these disorders ranges from indolent to very aggressive. Patients with symptomatic indolent T-cell or NK-cell LGL leukemia are usually treated with immunosu...
متن کاملLack of common TCRA and TCRB clonotypes in CD8+/TCRαβ+ T-cell large granular lymphocyte leukemia: a review on the role of antigenic selection in the immunopathogenesis of CD8+ T-LGL
Clonal CD8(+)/T-cell receptor (TCR)αβ(+) T-cell large granular lymphocyte (T-LGL) proliferations constitute the most common subtype of T-LGL leukemia. Although the etiology of T-LGL leukemia is largely unknown, it has been hypothesized that chronic antigenic stimulation contributes to the pathogenesis of this disorder. In the present study, we explored the association between expanded TCR-Vβ an...
متن کاملA Case Report: Large Granular Cell Leukemia/Lymphoma (LGL).
We presented a 64-year-old male patient with T-large granular cell leukemia/lymphoma with an agressive clinical course. Large granular lymphocytes were noted on peripheral blood smear. The phenotyping of the cells was typical T-cell lineage [CD2 (+), CD3 (+), CD5 (+)]. Clonal rearrangement of the T-cell receptor gene (TCR) was demonstrated by DNA hybridization technique. Large granular cell leu...
متن کاملLymphocytosis: T-cell large granular lymphocyte leukemia.
A 50-year-old female with low-grade chronic anemia and no other medical problems was evaluated when her hemoglobin fell to 8.2 g/dL. She had no adenopathy or hepatosplenomegaly. Her white cell count was 7.7 109/L with a lymphocyte count of 6.2 109/L, platelets 498 109/L, and reticulocyte count that was normal. Serum electrophoresis and rheumatoid factor were negative and ANA was weakly positive...
متن کاملDysregulated signaling, proliferation and apoptosis impact on the pathogenesis of TCRγδ+ T cell large granular lymphocyte leukemia
TCRγδ+ T-LGL leukemia is a rare form of chronic mature T cell disorders in elderly, which is generally characterized by a persistently enlarged CD3+CD57+TCRγδ+ large granular lymphocyte population in the peripheral blood with a monoclonal phenotype. Clinically, the disease is heterogeneous, most patients being largely asymptomatic, although neutropenia, fatigue and B symptoms and underlying dis...
